out with admirable skill. As regards R. trigyna, its tri- 
morphism has been described by Alefeldt (in Bot. Zeitung, 
18638, p. 281), and by Urban (in Brandenb. Abhandl. 1880, 
p- 18). There is also in the Kew Herbarium a beautiful 
series of specimens showing the various modifications in 
the length of styles and stamens, preparéd by Gen. 
Collett, F.L.S. (now commanding in Assam), and who, in a_ 
paper read before the Natural History Society of Simla, in 
1886, referring to R. trigyna and tetragyna, observes that 
the number of styles varies, and that the two species may 
not be distinct. ae 
ft. tetragyna has been long in cultivation in Kew and 
elsewhere, and forms a far finer decorative plant for the 
conservatory than any form of R. trigyna hitherto intro- 
duced, 
Descr. A glabrous shrub two to four feet in height, 
with terete branches and herbaceous branchlets. Leaves 
crowded near the tips of the branches, four to six inches 
long, spreading and decurved, elliptic lanceolate or 
oblanceolate, acuminate, obtusely serrulate or crenulate, 
narrowed into a short petiole, pale green ; nerves few, strong 
beneath, nervules reticulate ; stipules very minute. Flowers 
in terminal sessile corymbose cymes; pedicels half to one 
inch long. Sepals five, two-thirds of an inch long, elliptic- 
lanceolate, acuminate, concave, smooth, erect. lowers 
about two inches in diameter. Petals five, pale golden 
yellow, claws forming a tube longer than the calyx, each 
with a narrow membranous seed on the face; blade two- 
thirds to three-fourths of an inch long and broad, broadly 
obovate. Stamens five ; filaments slender, erect, united at 
the base into a short tube, with a short filiform staminode 
between each, and five glands at the base of the tube. 
Ovary subglobosé, three- to four-celled, each cell bilocel- 
late ; styles three to five, very slender, free or united slightly 
at the base, stigmas capitate; ovules one in eac. _ellus. 
Capsule globose, coriaceous, splitting into as mary © per- 
fectly two-celled one-seeded cocci as there are styles. 
Seeds angular, albumen a thin coat over the straight 
embryo.—J. D. H.
